I had asked Iadea if they could offer some insight on how to enter the IP. Here's the response I got from them:
If the user has XMP-3250/3350, please see bottom of page 4 in the User Manual under "Static IP – manually assign network IP address"
If the user has XMP-2200/2300, please see bottom of page 3 in the Firmware User Manual under "Static IP – manually assign network IP address"
